To all whom it may concern Be it known that 1, WILLIAM BLAoKMona, a citizen of'the United States, residing at Cleveland, Cuyahoga county, Ohio, have invented new and useful Improvements in Coupling-Supports, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 1s a side elevation partly in section, show ng my improved coupler support applied to a car coupler; Fig. 2 shows afront elevation of the coupler support, the

coupler being in section; Fig. 3 is a section: on lines III-III of Fig. 2 Fig. 4 shows an elevation of a modified form of my device;

Fig. 5 is a, section thereof, on lines VV of Fig. 4; Fig. 6 is a front elevation of a further modification;.and Fig. 7 is a section on lines VIP-VII of Fig. 6.

My invention relates to coupler supports particularly adapted for use with a radial draftgear, and consists in mounting the coupler on a rotatable member, which, in turn, is supported by the carry 1I'0I1. My

invention also consists in the construction and cotiperation of the various parts which I shall hereinafter describe and claim.

Referring to the drawings, 2 represents the carry iron bolted or otherwise secured to the end sills 3 of, the car. tion of the carry iron 2 is provided with a downwardly extending recess or pocket t, which is arc-shaped laterally, its center of curvature being coincident with the pivotal point of the draft gear. The rocker 5, the

lower face 6 of which is arc-shaped, with reference to its rounded upper end or hub i, has a bearing upon thetrack 8, which comprises the bottom of the pocket 4. The rocker 5 is also curved laterally to coincide with the curvature of the pocket 4. The lower face 6 of the rocker 5 has a plurality of teeth 9, preferably of less width than the face 6, which engage apertures 10 in the bottom of the pocket 4. The hub 7 of the rocker 5 engages a socket 11 in a hearing block or supporting plate 12. In the clock 12 are rollers 13, having axes at right angles to the longitudinal center line of the'coupler, the ends of which are of less diameter than their central portion, and are ournaled in bearings 14 in the upper face of the'plate 12. The housing15, within which".the coupler shank 16 is contained, is supported directly The central por- I upon the rollers 13, which; permit longitudinal movement of the housing and. coupler shank, with a minimum amount of friction. The ends 17 of the block 12 are turned up- Wvardly about the lower side faces of the housing 15, so that lateral movement of the housing will carry with it the-block 12 and the rocker 5. As the coupler moves laterally, carrying with it the block 12, the rocker 5 will roll along the track 8 of the pocket 1, and, because of the engagementof the teeth 9 in the corresponding. apertures 10 in the pocket 4, the rocker 5 will always be re turned to central, position. The engagement .of the teeth 9 with the apertures 10 willmaintain the rocker in its proper position in the pocket 4:, and will also prevent the rocker from sliding along the track. 8, or from becoming wedged in thepocket.

When the couplermoves longitudinally, under bufling or pullin stresses, the housing 15 is carried by the rol ers 13 in the beating block 12, which is held from longitudinal movement by its engagement with the rocker 5,,which, in turn, is held from longitudinal movement by its teeth 9, and the vertically extending walls of the pocket 4-.

In Figs.- 4 and 5 I have shown a modifica tion of my invention, in which I employ two rockers 5", which tend to give tlfe coui'er greater "resistance to twisting, the roe 1ers being arranged one on each side of thelongitudinal axls of the coupler, and bein mounted in pockets t on the carry iron 2 the centers of curvature of which are coin-' 6 of the rocker 5 is rounded in transverse section, to provide a socketed' bcaring in the floor of the recess 4?, and the apertures 10 are flared downwardly and outwardly to permit the tilting movement. in the lateral movement of the coupler the rocker 5 operates as in the preferred form, but in the lcngitudideparting from my nal movement the rocker acts as a link pivoted in the socket 18, and in the apertures 10 of the pocket 4 It is obvious that various modifications may be made in the constructions which I have shown and described herein, without invention.

-What I claim is:

1. In coupler supports, a draft member in combination with a laterally-movable rocker and a guideway therefor, a member intermediate the rocker and the draft member having an engagement with the rocker, and an anti-friction bearin on the draft member,

said draft member eing moved relatively to the intermediate member on said antifriction bearing and movable With the intermediate member laterally on said rocker.

2. In coupler supports, a coupler having a shank mounted for both longitudinal and lateral movement in a horizontal plane, a support for said shank, and a plurality of anti-frictional means mounted between said shank and said support, one of said means permitting said shank to have substantially non-frictional movement laterally in a horizontal plane, and the other of said means permitting said shank to have substantially non-frictional movement longitudinally in a horizontal plane.

3. In coupler supports, a coupler having a shank mounted for both longitudinal and lateral movement, a support for said shank,
